I’m always afraid I can not knit symmetrical or equal when I knit two or more parts separately in centimeters. I developed this pattern in rows and stitches to ensure I knit both hands exactly equal. Both hands are identical, and there is no difference between front or back side. The only difficulty is you have to count rows, but you are always counting rows and stitches when knitting… I made a written version and a little chart of the thumb increases For hands size M/L (women’s size)

Gauge: 10 x 10 cm = 27 sts. x 35 rows

Sock needles size 2.25 mm (I recommend a 15cm set for the hand and a 10cm set for the thumb) Stitch marker Stitch holder Crochet hook (2.5)
